Misinformation and China

February 2, 2026

March of the Chinese Volunteers

Key Questions

  • Did the United States use bacteriological weapons in the Korean War? What is at stake?
  • Disinformation and warfare: Are allegations of bio weapons a form political theatre? How are archives weaponized?
  • Official secrecy and plausible deniability: How do we know what we know? Do know what we don’t know? If so, how?

Korean War: Key dates

  • 1949-06: Soviet and American troops withdrawn; Kim Il-sung and Syngman Rhee endorsed
  • 1950-06: President Truman dispatched the 7th US Fleet to Taiwan Strait
  • 1950-06-25: North Korean Troops crossed the 38th parallel, eventually taking 90% of the south

International investigations

World Health Organization and International Red Cross

  • Investigations declined by North Korea and China

International Association of Democratic Lawyers’ commission

  • 1952 report: faced skepticism, partly due to the limited scientific expertise of its members

International Scientific Commission

  • Led by Swedish scientist Andrea Andreen, the Scientific Commission consisted of seven scientists from Europe, the USSR, and Brazil
  • Research in China and North Korea from June to September 1952
  • Report: US was engaging in bacteriological warfare in North Korea and China, albeit on a limited scale

Domestic impact of germ warfare

Patriotic Hygiene Campaign

Discuss: Germ Warfare and Patriotic Weisheng

  • What was the patriotic hygiene campaign?
  • “The weapon the Communists wielded against germ warfare was weisheng.” What was weisheng (public health)?

History of Bio Weapon Testing

1949:

  • scientists conducted a public test by releasing harmless bacteria in the air conditioning system at the Pentagon.

1950:

  • The US Navy sprayed the coast of San Francisco with two types of bacteria, Bacillus globigii and Serratia marcesens.
  • Bacillus globigii, then believed to be safe, now listed as a pathogen and can cause food poisoning.
  • Serratia marcesens caused serious bacterial infection; 11 hospitalized and one death.

History of Bio Weapon Testing, continued

1951:

  • Tests at Norfolk Naval Supply Center in Virginia; fungal spores were dispersed to study their effects on workers.
  • Workers mostly African-American
  • Scientists wanted to test a theory about their susceptibility to fungal disease compared to Caucasians.

1962:

  • Secretary of Defense Robert McNamara authorized Project 112 and increased testing and research on bioweapons.

1966:

  • Test on the New York subway; light bulbs filled with Bacillus globigii bacteria were smashed open on the tracks
  • 2008: the US Government Accountability Office acknowledged that tens of thousands of civilians may have been exposed.

Project 112

Chemical and Biological Defense: DOD and VA Need to Improve Efforts to Identify and Notify Individuals Potentially Exposed during Chemical and Biological Tests

GAO-08-366

Published: Feb 28, 2008

Congress has declined to take the actions suggested by GAO:

To provide greater transparency and resolve outstanding questions related to DOD’s decision to cease actively searching for the identification of individuals associated with Project 112, Congress may wish to consider requiring the Secretary of Defense to consult with and address the concerns of VA, veterans, and veterans service organizations; to conduct and document an analysis that includes a full accounting of information known, and the related costs, benefits, and challenges associated with continuing the search for additional Project 112 participants; and to provide Congress with the results of this analysis.

Discuss: Baseless

  • What do we know?
  • What don’t we know?
  • What don’t we know that we don’t know?

Protracted War

  • 1951-12: US agreed to negotiate cease-fire with mainland China
  • 1952-11 to 1952-11: US 8th Army bogged down during the Battle of Triangle Hill, with 20k+ casualties on both sides
  • 1952-11: President Eisenhower elected, promising swift end to war

Protracted War

  • 1953-02: President Eisenhower shifted American policy on “neutralization” of Taiwan to noose policy in retaliation of China’s refusal to accept armistice proposals
  • 1953-03: Death of Stalin
  • 1953-07-27: Armistice concluded, with 4-km demilitarized zone along 38th and exchange of PoWs

Legacies of Korean War

  • 600K Chinese killed, another 400K+ wounded
  • 36K Americans, 520K North Koreans, 400K South Koreans
  • Third deadliest war of the WWII
  • Costly conflicts: military expenditures comprising of 55% of gov spending, diverted from other programs
  • Divided Korea and Taiwan Strait

Legacies of Korean War, Continued

  • Boost to PRC prestige: China as a rising international power
  • Able to defend itself against superior American forces
  • Not just a dependent satellite of the Soviet Union
  • Revolutionary diplomacy: China as a protector and defender of non-Western countries
  • Regime consolidation, popular mobilization, and total transformation of Chinese society
